To all whom. 1'! may concern:

lle it known that 1. Mutual. E. .\l.\t o, eitizen of the United lilll$.residingat Greeley. in the eounty of \l'eld :mdfitate of t'ulumtlp. haveinvented vermin llGW and l useful lm|mwement-= in ('nrhureh-rs. of whiehthe following is a lm-itieationl y invention relate to earlmreters forexplosive engines and the ohjeetof my invention is the provision of anextremely simple eurlnm-ter 'llllll does away with the use of spring-hmmed valves and alm eliminates the Ilt't't 'll of using an air valve andwhit-h is therefore easy to l'ltilll and to keep in order.

further ohjeet is to provide a earlmreter which heeau e of its eoutrttrtion-nefil not he removed from the engine in order to he elemed andthe internal parts repaired.

.\ further ohjeet to provide a novel means for mixing the 'gm'stdenewith the air previous to the mixture being drawn into the engine.

A still further ohje t is to provide a earbuneter in u'hieh all of theinternal parts may he removed for eleauiug or for repair by simplyremoving the eap of the rarhureter. j

My invention shown in the aenmipanying drawing wherein:

Figure 1 is a rertieal sertiou thmugh my improved earhitreter. theinterior rah'e iug in elevation. Fig. 2 is a trultsfl-l'se seetion onthe line 2-: of Fig. I.

Referring to IE0 tigurts 2 designates the hotly of the, t-arllureter.having the shape of ahowlamlim-losing the earlnu-eting ehannher It.1111: upper portion of the 45 body of the rarhureter is'pnn'ided withthe outlet pipe I whit-h is to he miter-led to the engine in anysnitable'and desired manner. The bottom of the earhureter is providedwith inlet qaenings 5,. these inlet openings being a et] around aventral annular huh 6, the outer face of which is upwardly and centrallyThis hub 6 is provided with the tapering bore a to receive an inletvalve, as \rillfhe'lllel' described.

-Thehu h 6 extends down below the bottom l tremity of this outlet pipeof the earhureter, as at 8. and connected in any suitable manner to aninlet pipe extendmgfrom a mumof gasolt-ue. The inlet openmgs 5anarranged radialiy. as be fore stated, and extend downward and out-"ward from the central huh. The upper and lower faves of the inletports-or openings 5 are substantially parallel tueat-h other andupwardly and inwardly inclined. the upper faee of eaeh opening or portextending to' '8 the (ll'llllllftl'lllt't' of the lower end of theearhuteter. while the lower fare of each extends slightly beyond theupper and inner? edge of the upper fare. This permits the air to enterthe earhureter with requisite ease 7. but at the .qme time. bet-austofthe fact that the uptlllllgs do not extend directly downward, the vaporwill not he likely to escape fr m the air inlet penings.

The carhureting chamber 3 has a cylindri- 78 ml wall up to a pointnearly level with the outlet 'pipe and is there provided with an annularshoulder 9. Above the shoulder 9 the wall of the carhut'eter is pnu'idedwith W m h is fllaleld. asat It,
